I've done a few more shenanigans with the spinning angle changes conundrum - and here are pictures for you to look at.

Here's a pic of yarn before steaming:

and of a second bit of yarn after steaming:

and the same yarn used as weft for weaving a sample:

Weft is running vertically here, and the thing is quite weft-faced plain weave (I only had a puny frame with huuuuge warp spacing for the quick test...). I'd have preferred a more balanced plain weave, but well. Maybe next time.


In the weaving, the warp yarn was spun to about the same spinning angle, and the same thickness, only in the other direction. (Again - hitting an exact angle and keeping to exactly that angle is really hard, and there will always be digressions.)

So. Can you see differences?
